Intro

One month has passed since the infection spread across the world. You had been shut away in your room, but the food has run out. Your parents, who went out, have not returned. (They might not be alive anymore.) To survive, you have to go out.

From here on, you are free to proceed. Whether you meet a character or become a zombie, please continue as you wish.
